I rent a building in Ca for my baby store, my lease is up 7-31-10, I just gave my landlord 30 days notice, and he said that when he spoke to me 2 months ago I agreed to extend my lease verbally, I did agree to a month to month after my lease was up but never to a longer term, if I did why wouldn't I have got it in writing because on a month to month he can raise my rent? He is now saying he hold me to my rent till he finds another tenant, can he do this??
